This invention relates generally to a composite railroad tie or stringerand more particularly to a cross tie ofthe non-insulated type whichis'adapted to be embedded in the concrete of a street or road in such amanner that the top of the rail is disposed substantially level with thesurface of the street or road.

The main object of the invention is to pro- I videca simple, durable andefficient rail sup-J port which is made of; few partswhich are readilyassembled and disassembled and which is well adapted to quntityproduction at comparatively lowcostr A further object of theinvention is to provide a cross tie construction which consists A stillfurther obJect ofthe invention is to provide a strong anddependablecross 'tie construction in which the angle barsare bentupwardly at the central portion thereof and disposed in a planeconsiderablyabove 'the end portions thereof'whereby to reinforce theupper slab of concrete between; the rails.

A still further object of the invention is to provide a cross tieconstruction of thecharacter described in which the cross angle bars arebent upwardly between. the rails so as to require less concrete betweenthe rails and which is also provided with means for securelyanchoringthe rails to the central portion of the cross bars. j

' invention will appear as the description proceeds and by reference tothe accompanying drawing in which Fig. 1 is a top plan view of myimproved tie construction Fig. 2 is a view inside elevation of the tieshown in Fig. 1; Y 'Fig'. 3 is a view in end elevationof the tie shownin'Figs. 1 and 2 but on a smaller scale;

Fig 4 is a vertical-sectional view of aportion of a roadbed having my;improved tie arranged therein and Fig. 5 is a viewsimilar thereof so as.to reinforce the upper slab of fspaced'para'llel angle bars or crossbeams.

"plates 5 and 6 which fit withi'n the slots as f plates are secured inplace they will be dis- .preferably have portions 9 and 9? outthereneath the raiIs'are'SOmeWhat deeper-than the Further and morelimitedobjects of the remainlng portion; The tles are assembled to F ig.4 disclosing a modified form of'tie construction in which the centralportionsof the angle bars are deflected'upwardly and disposed in aplaneabovethe end portions concrete between the rails. p

' 'Referring now to the drawings thereference characters 1 and2'designatea pair of The. opposite ends of the angle bars 1 and 2 anddisposedat opposite ends thereof are rail shown most clearly in Figs. 1and 2. The rail plates 5' and-6are preferably welded to the angle bars,as shown most clearly in Fig. 2. The railplates 5 and 6 areeachjprovided with oppositely disposed pairsof'T-shap'ed slots 7, 8andfl7 8*. These slots are adapted toreceive the rail clamps therein forsecuring rails to the railplatesin a mannerto be here,- inafterdescribed. The slots 3, 3 and 4.14 T are. cut on slight angle so thatwhen the rail posed ata slight angle to each other so that when therails are secured thereto they will slope inwardly slightly in ordertoconform to the contourof they wheels. The rail plates from and bentdownwardly... therefrom as shown, which portions'serve to firmly embedthe tie in the concrete. Thetie maybe shipped in the disassembled or..knock-fdown condition soas to occupyv less space in shipping and may beassembled at thetrack side or at any other convenient place. e i

In forming the road bed a trench is provided in which the portionsimmediatelybeopenings 12 and 13'. After'thi's layer of'con 100 to I areprovidedwith slots 3, 4 and 3 4* respectively. Connecting the angle bars1 and2' drain ofi below the foundation.

' filled with bituminous concrete indicated at 14: in Fig. 1. Thismaterial consists of'slag and crude asphalt in about the followingproportions: 3 parts fine slag, 2 parts coarse slag and 1 part crudeasphalt. This material is waterproof and prevents water from seeping inadjacent or along the rail. The drain holes arefilled with gravel orcinders or other suitable material which permits the water to It is ofcourse understood that drain holes may be provided along'one or bothsides of the rails.

In Fig. 5 there is disclosed a slightly modis fied form of my invention.This form of the invention is substantially identical with the form ofthe invention shown in Figs. 1 to 4 inclusive except that the centralportions of the angle bars or cross beams are bent upwardly so as to bedisposed in a plane above the end portions thereof. The rail plates aresecured to the angle bars as described in connection with Figs. 1 to linclusive. Disposed adjacent the opposite ends of each of the angle barsare tie rods 15 and 16. The inner ends of the tie rods are preferablywelded to the central port-ion of the angle bars as shown at 17 and 18.The opposite ends of the tie rods are threaded and are adapted toproject through openings in the rails and to be secured thereto bynuts-19, 20 and 19 20*. These tie rods serve to strengthen and reinforcethe construction as a whole and to firmly secure the rails againstdisplacement. According to the preferred construction the centralportions of the angle bars are disposed in a plane about two inchesabove the end portions thereof.

This construction enables a thinner layer of concrete to be used betweenthe rails and provides a reinforcement for the comparatively thin upperlayer of material. It also effects a saving of concrete amounting toapproximately 350 cubic yards per mile which at present prices willamount to about $3,000.00 per mile.

'Various changes may be made in the details of construction and in themanner of assembling and securing the various parts in 7 place withoutdeparting from the spirit of my invention. Moreover, it should beunderstood that my invention is not' limited to any particular type ofroad surface or foundation as different materials may be used accordingto the nature of the track and according to the load the trackisintended to withstand. It is therefore understood that my invention islimited only in accordance with the scope of the appended claims.
